## com.sas.iquery.metadata.business.step
Class CompoundStep

    com.sas.iquery.metadata.business.step.CompoundStep

All Implemented Interfaces:
  Base, BusinessModelResourceReferencer, ModelItem, StepInterface, UsabilityInterface, PropertyChangeListenee, com.sas.util.LocalizableToStringInterface, java.beans.PropertyChangeListener, java.lang.Cloneable, java.util.EventListener

    public class CompoundStep

implements StepInterface, java.lang.Cloneable, com.sas.util.LocalizableToStringInterface

Enables a user to group a set of steps together. A compound step brings the notion of parentheses within the list of steps. For example, (Blue Car Models with Sales GT 1M) and (Red Car Models with Sales GT 2M). CompoundSteps, like simple Steps are managed by the StepManager. Each CompoundStep can contains any number of Steps or CompoundSteps.

The following is a brief description of how AND/OR is applied by step

- OR condition for filter is: Filter( (Blue Car Models with Sales GT 1M) OR (Red Car Models with Sales GT2M) )
- OR condition for ranking is: {TopCount(Blue Car Models Top 25), BottomCount(Blue Car Models Bottom 25))
- OR condition for navigation is: Union(Blue Car Models.children, Red Car Models.children)
- OR condition for a mixed steps of ranking and filter is: Union(TopCount(Blue Car Models Top 25), Blue Car Model with Sales GT 1M)
- OR condition for a mixed steps of ranking and filter using NOT: Except(TopCount (Blue Car Models Top 25), Blue Car Model with Sales GT 1M)

- AND condition for filter is: Filter( (Blue Car Model with Sales GT 1M) AND (Red Car Models with Sales GT 2M) )
- AND condition for ranking is: {TopCount(BottomCount(Blue Car Model, 100), 25)}
- AND condition for navigation is: Intersection(Blue Car Model.children, Red Car Models. children)
- AND condition for navigation using NOT is: Intersection (Blue Car Model. children, Red Car Models. children)
- AND condition for mixed steps of ranking and filter is: TopCount(Filter(BlueCar Model with Sales GT 1M), 25)
